503 error (Service Unavailable) in the jetty server

Question

What is the solution of 503 error (Service Unavailable) in a Jetty server. I am using jetty with the eclipse IDE besides the GWT as front end tool.

At the same time my one module is running good, but when I try to run my second module which is error free, I get the error 503 service unavailable.

I don´t know much about jetty but while informing me about it (what it is and what it does) I found this in a wiki:

If jetty fails to show the expected pages when you try to login, and gives a 404 or 503 error, this can be caused by an error in one of the configuration files, especially etc/snmp-graph.properties. The place to look is logs/daemon/output.log.
